San Francisco. Two companies from Taiwan and Aachen are developing a ceramic battery with the shortest charging time. The technology is ready for the market, but the price is not yet.
A company from Taiwan wants to bring a battery onto the market in 2027 Electric cars significantly upgraded. It charges from five to 60 percent in five minutes. This would allow a driver to travel an average of 300 kilometers. It would be particularly advantageous on long journeys – a weakness of electric cars so far.
The technical solution is largely beyond question. The TÜV Rheinland Has certified the technology and confirmed the performance data. The question arises as to whether it is economical; cheaper than standard lithium-ion cells.
The manufacturer ProLogium pushes the project. Um hat
- The battery on the Paris Motor Show Presented in mid-October;
- 8,000 sample cells worldwide Automobile companies delivered; delivered;
- cave Building a factory in Dunkirk, France.
The innovation: ceramic batteries
The Taiwanese are working with a German company: FEV from Aachen. They come from ProLogium cells and die from FEV Battery systems. Aachen has developed into a battery research center in the vicinity of the university.
Electric cars run on lithium batteries. The negatively charged electrode of a battery is made of carbon-based materials, usually graphite. Instead, the Taiwanese rely on an anode made of a silicon material, resulting in: Ceramics.
Lower risk of fire
It is ten times higher Capacity density and a larger one Energy density than previous batteries. This explains the shorter charging times and greater range: from five to 60 percent in five minutes, and after another 3.5 minutes the capacity is 80 percent.
For comparison. In August the ADAC had 20 cars Fast charging tested at 80 percent. With a charging time of 20 minutes, the performance values were significantly lower.
Advantage in maintenance
As FEV's head of communications, Ulrich Andree, explained to our editorial team, the Ceramic battery other advantages. Firstly, it is flat and lighter. This means: the same performance with smaller batteries. This gives you space. Or: More performance with the same size. A huge plus, especially for small cars and hybrid vehicles.
Second, the battery doesn't burn. Third: Since it is modular, the entire battery pack does not have to be replaced in the event of damage – only individual cells (groups). That should Service, maintenance and repair Make it much easier.
Cars have to be good on long journeys
The demand for electric cars is stagnating. In October their sales in Germany even fell. There are many reasons for this, loading times being one of them. The shorter they are, the better more suitable for long distances is the car. The argument counts, especially in Germany with its large motorway network and demanding car customers.
In addition, the shorter the charging time, the faster a driver can die Charging station leave. It would relieve the load on the network of fast charging stations, which is rather undersized in Germany.
The “small battery” concept But it only has a future if it's worth it. Andree admits that market prices for the technology are “still relatively high”. The reasons for this are the complex manufacturing and limited production capacities.

For widespread use, the technology must be economical. Unit costs decrease as production increases and investments are made in automated production lines. How competitive can the ceramic battery be? Vincent Yang, who founded ProLogium in 2006, says confidently: “Our goal is to fundamentally change the market.”
